nited States Patent 2,8 i ,544 Patented Dec. 10, 1957 This inventionrelates to a window frame construction.

It is a principal object of this invention to provide a window frameconstruction to permit quick removal of the window sash for a buildingor house or the like wherein the vertically slidable sashes of a doublehung window may be readily removed, one sash inside and the other sashoutside, of the building when the sashes are slid to the limit of theiropen position.

Another object of this invention is to provide a removable window sashhaving a frame with vertically sliding window sashes therein, the sashesand frame being so constructed and related to each other that the sashesmay be removed from the frame for cleaning, painting or repair withinthe building when removed from the frame.

A further object of this invention is to provide a Window frame of thiskind having sashes removable readily to receive a shielding to preventinjury to the occupants and to the building itself from a suddenincrease or decrease of pressure on the window as from an adjacentexplosion of a bomb.

Other and further objects and advantages of the invention will behereinafter described and the novel features thereof defined in theappended claims.

Fig. 8 is an isometric view of an end of the lower window sash.

This is a removable window sash of the double hung variety. Theremovable feature is to facilitate the easy emergency placing of variousshieldings (not shown) on the outside of the sash and glass, the primepurpose of this invention being defense of life and property and thesaving of our cities by blocking and resisting firestorm, and furtherconsiderable bomb burst pressures and violance but also to hold thebuildings tight against poisoned atmosphere of biological and gaseouswarfare. The removable sash advantage is most advantageous for upperstories of buildings, skyscrapers, etc. The added shieldings form apeacetime storm sash capable not only of holding the building tightagainst cold and heat but also inclement weather. Added to this thechief purpose is the defense of our cities and its people to hold wilddestruction from building up its furies into unstoppable proportionswhich roll onwards and over everything until there is nothing more to bedestroyed of life and property and the cities are leveled.

The removable mechanical principal can be easily produced at a very lowcost but obviously the low cost and easy way of handling the windowleaves very much to be desired because the takeout principal is therefor its advantages other than mere removability.

In order to accommodate the above noted functions of my removable windowthere is provided a window structure 10 having a frame 11 withvertically extending jambs 12 therein. The jambs are connected togetherat their upper end by a horizontally extending header 14 and at theirlower end by a horizontally extending sill 16. Each jamb 12 is formedadjacent the upper end thereof with a transverse channel 30 within whichthe ends of header 14 engage and each jamb 12 is formed adjacent itslower end with a transverse channel 31 in which the ends of sill 16engage. In order to stiffen the window frame 10 there is provided ametal strap 17 which substantially engages the side edges or walls ofthe jambs 12 and extends horizontally thereacross at the rear endthereof. The straps 17 will substantially stiffen the jambs 12 so thatthe window frame 11 may withstand all of the conditions to which thewindow may be subjected.

In order to more substantially reinforce and stiffen the jambs 12 thereis provided a removable guard plate or backpiece 18 which is secured toeach of the jambs on the inner side thereof by the screws 19. Thebackpiece may be removed from or re-inserted into the window frame 11 bythe removal or placement of the screws 19.

A parting strip 20 is positioned on the back plate or back piece 18midway along the width of the guard plate and the sashes are separatedby the parting strip 20 in a conventional manner.

L-shaped check stops 21 are disposed in overlying position with the backpiece 18 and each extends substantially half of the length of the jamb12 to which it is attached.

The stops 21 are only half the length of jamb 12 so as to be disposed inconfronting position to the upper and lower sashes, when the latter arenormally closed. The cutting off of the stops 21 permits the removal ofthe upper and lower sashes when disposed in fully open position.

The check stops 21 each includes a base 22 which overlies the jamb 12and has an upstanding way section 23 and an outwardly extending flange24 to form the L- shaped side check stop 21 to hold the window sash inposition for sliding movement.

The base arm 22 is raised at the end adjacent Way section 23 to form acloser fit to steady the respective upper and lower window sashes whenmoved to their closed position in the window frame 11.

As each of the window sashes is movable by sliding vertically in thewindow frame 11 a guide stop 25 is secured to each back piece 18 on thefree edge as an extension of check stop 21, for holding check stop lug29 on the window sash within the window frame.

The lower sash 26 is slidable within the window frame 11 and backpieces18 and cooperates with the upper window sash 27 so that when the lowerwindow sash 26 is completely moved to its lowermost position and theupper sash 27 is slid to its extreme vertical position, the window willbe closed.

In order to remove the upper and lower window sashes from the windowframe, the window sashes are moved to their completely open position.There is provided a horizontally extending cutout notch 28 at the freeend of each of the guides 25. When the lower window sash 26 is moved tothe top the stop lug 29 is located adjacent the cutout notch 28 at theupper end of the window frame. In this position the lower sash is pulledinwardly and out of the frame, as the lug 29passes through'cutout'n0tch'28. Similarly, the upper sash is taken out at the bottomof the frame in an outward direction.

While the specific details :of one embodiment of this invention havebeen herein shown .and described, the invention is not confined theretoas changes. andaalterations may be made 'without departing'fromtthe.spirit and scope thereof as-defined in the-appended claims.

What is claimedIis:

'1. -In a Window frame structure-having'apair of vertical jambs, anelongated verticahplate fixed \to the inner face of each jamb, .aninwardly projecting flange extending from each verticaledge ofsaid,plate,-a parting-stopfixed to said platezmidway betweensaidtflanges,-.a,pair of plates fixed to said firstplate, oneon eachside zofsaid parting stop, .each'of said pair ofplates.havingazlengthsubstantially one-half thezlength :of said firstnarnedplate, one of said pair .of plates :beinganlinner plate-and extendingupwardly from the lower end of-said first namedplate, the other of:saidpair of plates being an outerplate and extending downwardly from.the lower .end of said first named plate, a right angular.flangecarried by said inner plate and constituting.an.-inner stop,.aright angular .flange carriedby said outer plate and constituting anouter stop, and -a laterally projecting flange extending from each rightangular flange.

2. The structure set forth in claim 1 wherein each of said first namedflanges is formed with a cutout adjacent one end, the cutout in oneflange being oppositely disposed relative to the cutout of the otherflange, inner and outer sashes engaging between said .inner and partingstops and said outer and parting stops, and a sash retaining lug carriedby each sash adapted upon disposing of a sash in completelyopenvposition to be disposed in registry with a cutout whereby the sashmay be removed from the frame.
